FIELD OF THE INVENTION

Certain embodiments of the invention relate to broadband gateways. More specifically, certain embodiments of the invention relate to a method and system for multi-transport and multi-protocol processing in a broadband gateway.

BACKGROUND OF THE INVENTION

With the continuous growth of digital television or broadcast multimedia, and/or broadband access, which may be used in conjunction with online businesses, social networks, and/or other online services and applications, users may desire having access to a larger number of providers and/or a broader range of content in a manner that is flexible and/or suits the users' lifestyles. Most users connect to the Internet using web browsers running on personal computers (PCs). Furthermore, most households may have one or more televisions that may be used to view television and/or multimedia broadcasts. Television broadcasts may include terrestrial TV, Cable-Television (CATV), satellite TV and/or Internet Protocol television (IPTV) based broadcasts. To ensure against unauthorized reception and/or use of TV and/or multimedia broadcast, service providers may require use of dedicated set-top boxes (STBs) that may be used to encrypt broadcast signals communicated from the service providers to generate suitable video and/or audio streams that may be played via televisions and/or other display/playback devices in the household. Furthermore, STBs and/or TVs may support Internet access. Thus, rather than using a computer to access the Internet, a user may find it more convenient to use the flat screen televisions and/or monitors in homes for the same purpose. To do so, for example, an STB connected to a flat screen television may be provided with web browsing software and protocols, and Internet connectivity, which may enable the user to easily access the Internet or check their electronic mail (email), for example, from a convenient and comfortable location such as their living room.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

In various embodiments of the invention, a broadband gateway, which enables communication with a plurality of devices, is operable to handle at least one physical layer connection to at least one corresponding network access service provider. In this regard, the at least one physical layer connection may comprise a plurality of physical layer connections and the at least one corresponding network access service provider may comprise a plurality of access service providers. Each of the plurality of physical layer connections corresponds to a respective one of the plurality of corresponding access service providers. The broadband gateway may receive a packet from a plurality of network access service provider over a corresponding physical layer connection. The broadband gateway may determine which one of a set of possible transport protocols is utilized for the received packet. The determined transport protocol may be utilized to identify content within the received packet. The set of possible transport protocols may be selected and/or determined based on, for example, a channel type identified for the physical layer connection. The selected set of possible transport protocols may be utilized, either sequentially or in parallel, to filter the received packet. The selected set of possible transport protocols may be ranked, for a serial transport process, based on service priority, for example. The received packet may be filtered utilizing the selected set of possible transport protocols, one at a time, based on the ranking. For a parallel transport process, the selected set of possible transport protocols may be concurrently utilized to filter the received packet. The content identified for the received packet may be marked utilizing the determined transport protocol for content distribution.

FIG. 1 is a block diagram illustrating an exemplary communication system that comprises a home network serviced by a broadband gateway, in accordance with an embodiment of the invention. Referring to FIG. 1, there is shown a home network 100 a, a plurality of distribution networks 110, a plurality of service providers 120, and a plurality of content providers 130. The home network 100 a may be serviced by a broadband gateway 102. Also shown in FIG. 1 are additional home networks 100 b, . . . , 100 n. Each of the home networks 100 b, . . . , 100 n may also be serviced by a broadband gateway 102.

For example, the Internet 110 a may enable connectivity among a plurality of private and public, academic, business, and/or government nodes and/or networks. The physical connectivity may be provided in the Internet 110 a via, for example, the Public Switched Telephone Network (PSTN), copper wires, fiber-optic cables, wireless interfaces, and/or other protocols and/or standards-based interfaces. The transport functionality may be performed in the Internet 110 a based on, for example, one or more protocols, such as the Transmission Control Protocol/IP (TCP/IP), for example. The CATV network 110 b may comprise suitable distribution nodes, systems, and/or subnetworks that may enable forwarding of communication between CATV providers and a plurality of cable-TV consumers. For example, the CATV network 110 b may comprise a network of fiber optics and/or coaxial cables for use in CATV broadcasts. The satellite TV network 110 c may comprise suitable distribution nodes, systems, and/or subnetworks that may enable communication of satellite TV broadcast by satellite TV providers to a plurality of consumers. For example, the satellite network 110 c may comprise a plurality of orbiting satellite nodes and/or one or more terrestrial centers in a satellite-TV system.

The LAN/WAN network 110 d may comprise suitable logic, circuitry, interfaces, and/or code that may be operable to enable implementation of one or more wired and/or wireless LAN or WAN standards and/or protocols. Exemplary WAN technologies comprise, for example, WiMAX-based networks. Exemplary LAN technologies may comprise, for example, those based on IEEE 802.11 standards, including, for example, WiFi-based networks. The cellular network 110 e may comprise suitable logic, circuitry, interfaces and/or code that may be operable to enable communication via one or more cellular technologies.

The cellular network 110 e may comprise, for example, a plurality of control and/or switching nodes, and a plurality of base stations that enable transmission and/or reception of cellular based communications between the cellular network 110 e and cellular capable devices.

The home network 100 a may correspond to a location that may comprise a plurality of devices 104 which may be serviced and/or managed by the broadband gateway 102. In this regard, the location may be a residence (e.g., home, apartment), a small business, a school, a library, and/or other like settings in which users may want to obtain access to service and/or to content provider networks. The broadband gateway 102 may be utilized in the home network 100 a to provide connectivity between the home network 100 a and the service providers 120 (and/or the content providers 130) via the distribution networks 110.

The broadband gateway 102 may comprise suitable logic, circuitry, interfaces, and/or code that may be operable to provide connectivity between one or more devices in a home network, such as the home network 100 a, and a plurality of external networks. For example, the broadband gateway 102 may handle a plurality of broadband physical layer connections 108 to the distribution networks 110. The broadband physical layer connections 108 may comprise wired, optical, and/or wireless connections between the broadband gateway 102 and the distribution networks 110, which may enable communication between the broadband gateway 102 and the service providers 120. The broadband gateway 102 may operate as an interface device that may allow one or more service and/or content providers to interact with various devices in the home network. In this regard, the broadband gateway 102 may be operable to perform and/or provide various services that may pertain to enabling and/or facilitating reception of content from one or more content providers, wherein the content may be delivered through one or more services providers.

The broadband gateway 102 may communicate with various devices in the home network 100, using wired and/or wireless communication links.

A single broadband gateway 102 may be operable to handle multiple physical layer (i.e., layer 1 of the open-systems interconnection model (OSI)) connections 108 to multiple ones, or portions, of the distribution networks 110, where different ones or portions of the distribution network(s) 110 are owned, operated, leased, or otherwise associated with different network access service providers 120. For example, a first network access service provider 120 may provide network access to the gateway 102 via a DSL connection over twisted-pair cabling, and a second network access service provider 120 may provide network access to the gateway 102 via a cable television connection over coaxial cabling. In some instances, the gateway 102 may be operable to concurrently communicate over multiple physical layer connections provided by multiple network access service providers.

The broadband gateway 102 may also be operable to provide and/or support various other, non-content related services in the home network 100. For example, the broadband gateway 102 may be operable to provide energy management in the home network 102, by controlling and/or adjusting configuration of one or more devices in the home network to reduce power consumption for example.

Devices serviced by, and/or connected with the broadband gateway 102 may comprise content consuming devices and/or other, non-content consuming household or home devices that may be operable to interact with the broadband gateway 102. For example, the broadband gateway 102 may service, and/or may communicate with a plurality of home devices 104 a-104 j in the home network 100 a.

In the exemplary embodiment of the invention illustrated in FIG. 1, although the devices 104 a-104 j, may communicate only the broadband gateway 102 as shown, the invention may not be so limited. Accordingly, the devices 104 a-104 j, may communicate with multiple broadband gateways in a local or home network without departing from the spirit and scope of various embodiments of the invention.

As illustrated in FIG. 1, a plurality of home networks 100 b, . . . , 100 n, may also be connected to the distribution networks 110. These home networks 100 b, . . . , 100 n may operate in substantially the same manner as the home network 100 a. By having multiple home networks connected to the distribution networks 110, various applications, such as peer-to-peer communication and/or data aggregation operations may be possible by utilizing the broadband gateways 102 in the home networks.

In operation, one or more intended devices such as the device 104 a associated with the broadband gateway 102 may request that content be delivered to it via the broadband gateway 102. The broadband gateway 102 may communicate with the content providers 130 and/or the service providers 120 for the content requested by the device 104 a.

In an embodiment of the invention, the broadband gateway 102 may support and/or perform multi-transport processing on packets received from the corresponding content providers 130 and/or service providers 120 over a plurality of physical layer connections. The broadband gateway 102, before allowing the device 104 a to access the requested content in the received packets, may learn or monitor traffic behavior such as past or current traffic patterns and/or traffic volume between the associated networks and the device 104 a to identify or determine channel types for the plurality of corresponding physical layer connections. The identified channel types may comprise, for example, Cable linear broadcast, IP satellite, and/or video on demand (VoD). For each of the identified channel types, the broadband gateway 102 may determine or select multiple most possible transport protocols such as MPG, MP2, MP3, MP4, MPEG, AVI, MPA, MPV, WAV, AU, WMA, WMV and/or ASF that may be utilized by the content providers 130 and/or the service providers 120 for the received packets. The broadband gateway 102 may be operable to utilize the selected multiple transport protocols to filter or multi-transport process the received packets in order to identify or search for content in the received packets. A process of filtering the received packets utilizing multiple transport protocols is referred to as a multi-transport process. In instances where the received packets are IP encapsulated by the content providers 130 and/or service providers 120, the broadband gateway 102 may transcode the received packets before performing multi-transport processing on the received packets.

In an embodiment of the invention, the broadband gateway 102 may perform serial or parallel multi-transport processing on the received packets depending on gateway configuration. In instances where a serial multi-transport process is supported by the broadband gateway 102, the broadband gateway 102 may be operable to sequentially perform transport processing on the received packets utilizing selected multiple possible transport protocols. In this regard, the broadband gateway 102 may rank or sort the selected multiple possible transport protocols based on, for example, service priority, content quality, price, QoS, gateway configuration and/or device profiles. The device profiles may comprise device capability such as network protocols supported by the devices 104, device power consumption information and/or user preferences. The broadband gateway 102 may perform transport processing sequentially on each of the received packets according to the ranking or sorting of the selected multiple possible transport protocols. In instances where a parallel multi-transport processing is supported by the broadband gateway 102, the broadband gateway 102 may perform parallel or distributed transport processing on each of the received packets utilizing the selected multiple possible transport protocols.

In an embodiment of the invention, the broadband gateway 102 may be operable to identify or discover correct transport protocols that may be utilized by the content providers 130 and/or service providers 120 for the received packets. In this regard, the broadband gateway 102 may check fields of the received packets utilizing the selected multiple possible transport protocols to determine or discover the correct transport protocols utilized by the corresponding content providers 130 and/or service providers 120 for the received packets.

In an embodiment of the invention, the broadband gateway 102 may search for or identify content in the received packets utilizing correct transport protocols determined through transport processing on the received packets. The identified content may be marked utilizing the determined correct transport protocols and may be provided to the devices 104 for content consumption.

FIG. 2 is a diagram illustrating an exemplary broadband gateway, which may be operable to perform multi-transport and multi-protocol processing on packets received from a plurality of corresponding network access service providers over a plurality of physical layer connections, in accordance with an embodiment of the invention. Referring to FIG. 2, the broadband gateway 102 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to provide connectivity between one or more networks, such as the distribution networks 110 shown in FIG. 1, for example, and one or more devices in a home network, such as the home devices 104 a-104 j in the home network 100 a shown in FIG. 1. In this regard, the broadband gateway 102 may operate as an interface device that allows one or more devices in the home network to access one or more networks, and to access various services and/or content via those one or more networks. For example, the broadband gateway 102 may be utilized to enable interaction between the plurality of service providers 120 and/or the plurality of content providers 130, and the home devices 104 a-104 j.

The broadband gateway 102 may communicate with the various devices via a home network that may comprise wired and/or wireless communication links, such as the home network 100 a. In this regard, the broadband gateway 102 may comprise suitable hardware and/or software to provide some or all of the functions and/or operations of one or more of a modem, a router, and a switch.

The router functions and/or operations may be those of a wireless router, for example. The switch functions and/or operations may be those of a network switch, or a local area network (LAN) switch, for example. In some instances, the broadband gateway 102 may communicate with the various devices in the home via more than one home network.

The broadband gateway 102 may be operable to provide energy management by varying the configuration of one or more devices in the home network. The broadband gateway 102 may collect and/or store energy-related information of the devices in the home network and/or of the links in the home network, and may utilize such information to control the operation of the home devices. For example, the broadband gateway 102 may utilize channel capacity flexibility and content coding options to minimize and/or optimize power utilization. The broadband gateway 102 may also configure and/or manage the configuration of the network between the broadband gateway 102 and one or more service/content providers based on the energy-related information associated with the devices in the home. For example, at least a portion of the distribution networks 100 may be configured and/or managed in this manner. The broadband gateway 102 may be utilized to display energy-related metrics, including consumption trends and/or costs, for example, and to display any available credits/rewards that may be redeemed by a user. In some instances, when a device in the home network is a certified device, such as a California efficient display, for example, the broadband gateway 102 may be utilized to provide that information to a service/content provider and obtain rewards/credits associated with the use of such certified devices. Moreover, overall network power consumption may be managed by sharing information among multiple interconnected broadband gateways.

The broadband gateway 102 may be operable to adapt and/or enable changes in a subscription model and/or in multimedia delivery characteristics based on the capabilities of the various devices in the home network. For example, high-definition video content may be delivered to certain type of devices, such as digital televisions (DTVs), while low-definition video content and/or text may be delivered to a different type of devices, such as personal mobile devices. In this regard, the broadband gateway 102 may be utilized to reduce bandwidth and/or processing power consumption in the home network. The broadband gateway 200 may also support and/or use multi-transport processing, which may be performed sequentially, in parallel, and/or utilizing distributed processing.

The gateway functionality associated with a user, such as security features, preferences, applications, electronic programming guides (EPGs), and user profile, for example, may be ported from the broadband gateway 102 to one or more other broadband gateways 102 in other locations.
